Air bag type floating bridge reinforced by cables

Abstract

An air bag type floating bridge reinforced by cables comprises a bridge span structure, an air bag and a reinforced combined structure. The bridge span structure is connected to the top of the air bagto form a bridge section unit; the adjacent bridge span structures are connected in a hinged mode to form the air bag type floating bridge. Reinforcing combined structures are arranged on the two opposite sides of the air bag type floating bridge. The reinforcing combined structure comprises a supporting frame, a movable supporting rod and a reinforcing cable. The two sides of each bridge span structure are each provided with a supporting frame. A movable supporting rod is arranged in one supporting frame, and the supporting frame and the movable supporting rod form a supporting frame structure; the reinforcing cables are connected between every two adjacent supporting frame structures. By combining with other structures or methods, when a vehicle passes through, the reinforcing cables are pulled to pull a plurality of surrounding bridge sections to sink under stress, so that the condition that the sinking amount of only one or two bridge sections of the original air bag type floatingbridge is large is improved, and the stability and the bearing capacity of the air bag type floating bridge can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of pontoon bridges, and also to the technical field of pontoon bridge strengthening, in particular to an airbag-type pontoon system reinforced by cables and a method for using the same. Background technique [0002] The pontoon bridge is an important form of bridge, usually composed of multiple bridge sections. It is low in construction cost and fast in erection, and plays an important role in both civilian and military fields. The structure of the airbag pontoon is simple, and the buoyancy is provided by the airbag, which can effectively reduce the weight of the pontoon and facilitate transportation, so it has been widely used. [0003] The airbag composite pontoon bridge is usually an articulated system. When vehicles pass, only the two bridge sections adjacent to the load are under greater stress. The carrying capacity of the pontoon bridge has been greatly affected, and the safety and comfort of drivin...

AI Technical Summary

Problems solved by technology

[0003] The airbag composite pontoon bridge is usually an articulated system. When vehicles pass, only the two bridge sections adjacent to the load are under greater stress. The bearing capacity of the pontoon is greatly affected, and the safety and comfort of driving are also seriously affected.
